[SWDEV-531904] - Added GPU Cache Read Tests (#464)

New:
- gpu_cache_read.h and gpu_cache_read.cc
- Test reads GPU cache info and asserts valid structure
Updated:
- integration_test.py
- Added test_gpu_cache_info() and asserts valid structure
- test_get_gpu_compute_partition() to loop through all devices when test fail/pass
Added:
- test_get_gpu_compute_partition_returns_string() to integration_test.py
- This test displays the current compute partition for each bdf
